A Landowner’s Guide to Careful Logging
1.0 Introduction
Woodlot owners harvest trees for many reasons: to
generate income; produce lumber or firewood for their
own use; create recreational trails for skiing, snowmobiling
or hunting; improve wildlife habitat; or just to maintain the
health of their forest. Whether any of these reasons apply to
you, one thing woodlot owners have in common is a strong
desire to do what is right for their land — that’s why the
Ontario Woodlot Association created A Landowner’s Guide
to Careful Logging.
Most woodlot owners are not forestry or logging
experts, yet they are often involved in harvesting activities.
This guide offers a clear, practical overview of careful
logging practices, or CLPs, both for the novice and
professional logger. However, it is not intended to be a
definitive logging manual.
Section 1.0
The choice of silvicultural system (e.g., harvest and
regeneration) depends on characteristics unique to each
woodlot. This decision is influenced by factors such as stand
and site conditions, forest health, management objectives,
markets, wood-processing requirements and the size and
intensity of a harvesting operation. The breadth and range
of these factors means that this CLP guide cannot answer all
of your questions and that a number of silvicultural systems
(selection cutting, shelterwood cutting or clear-cutting) may
be appropriate for logging operations in southern Ontario.
A Landowner’s Guide to Careful Logging provides
landowners with sound advice as they make decisions
to protect the health and integrity of their woodlots, while
maximizing financial returns. It also identifies some of
the relevant federal and provincial legislation, as well as
regulations and municipal bylaws applicable to logging on
private land.

How to use this guide
Throughout the guide, there are “Stop Signs” that alert
the reader to potential legal requirements, “Caution
Signs” that point out important information that should
not be overlooked and “Tips” to identify elements
that may warrant further consideration.
Italicized words are defined in the Glossary of Terms.
The appendices provide additional information under
the titles of Legislation and Regulation (Appendix 1),
Sources of Information and Assistance (Appendix 2)
and Logging Damage Guidelines (Appendix 3).
What are careful logging practices?
Look for these
symbols for
special alerts,
information
and tips
Careful logging practices (CLPs) include a range of
techniques and practices used by landowners and loggers
to minimize damage to the forest, soil, wildlife habitat and
water. Examples of CLPs include directional felling of trees,
erosion control measures on skid trails, tree protection for
wildlife and the establishment of buffers near water.
When properly implemented, CLPs benefit the
woodlot by:
✥✥protecting and/or maintaining forest health and
productivity by reducing site impacts and logging
damage to residual trees and other vegetation;
✥✥protecting and/or maintaining other forest values and
features such as wildlife habitat, streams, woodland pools
and wetlands; and
✥✥maintaining the ecological functions of the woodlot.

A Landowner’s Guide to Careful Logging
2.0 Planning for Harvest Operations
This section describes two distinct kinds of woodlot planning.
A woodlot management plan is a long-term, strategic
document, which includes a detailed inventory of the
woodlot, the landowner’s objectives and a series of activities
that will help to achieve these objectives over time. A harvest
plan is a one-time, technical document, written to plan a
specific operation on the property, and ensures that harvest
activities are well-thought-out prior to implementation.
Section 2.0
Woodlot management plan
All woodlot owners
should create, implement
and maintain a woodlot
management plan. A
properly prepared and
implemented plan will
help woodlot owners to
maximize the ecological
and economic benefits
obtained from their forest
property.
Information on preparing a
woodlot management plan can
be found in A Guide to Stewardship
Planning for Natural Areas. Refer to
Appendix 2 to find out where to get a
copy of the guide and for assistance
in preparing a plan.
3

A Landowner’s Guide to Careful Logging
The content of the management plan will vary according
to ownership objectives, woodlot characteristics and the
financial resources available for the preparation of the plan.
As a minimum, the management plan should contain the
following:
✥✥a property and forest stand map;
✥✥a description of the woodlot (including legal description)
and its history;
✥✥a statement of the woodlot owner’s management
objectives;
✥✥information on the type, location and quality of resources
in the woodlot (e.g., forest inventory, wildlife habitat,
significant features); and
✥✥a schedule of activities that are planned to take place,
typically for a five- to ten-year period.
Harvest planning
Harvesting and other forest management operations (e.g.,
tree marking or thinning) that are to be implemented in the
woodlot, are outlined in the schedule of activities section
of the woodlot management plan. A second document,
the harvest plan, provides much greater detail about these
operations. A harvest plan should ensure that operations are
appropriate for the individual woodlot and are carried out
according to the landowner’s objectives, relevant legislation,
principles of good forestry practices and recommended
careful logging practices.

A Landowner’s Guide to Careful Logging
Section 2.0
Proper planning for harvesting and the layout of roads, trails and landings
will protect woodlot values and improve the financial bottom line of the
logging operation.
Engaging a reputable consultant and/or logger can help
ensure that logging operations are conducted in accordance
with good forestry practices and that other values in the
woodlot are protected and/or maintained.
5

A Landowner’s Guide to Careful Logging
Landowners
should be aware
that some forestry
consultants work
independently,
while others are
employed by the
forest industry.
When hiring a
forestry consultant,
landowners should
seek out a member
of the Ontario
Professional
Foresters
Association
to ensure that
professional
standards are met.
Before you start harvest planning, you need to evaluate your
role in these activities. Landowners possess a wide variety
of skills and knowledge and have different interests and
expectations of their role in forestry operations.
Landowners who have been trained in forestry or logging
may choose to carry out operations on their own. Others
may choose to seek out the services of a well-trained and
conscientious forest consultant and/or logger to assist them
with this process. This decision should be made before you
begin harvest planning.
Hiring a consultant
Local forestry consultants can assist landowners in all
aspects of woodlot management and planning. Consultants
can provide expert advice, independent of the logging
contractor. In many instances, forestry consultants will offer
a range of services associated with logging, such as timber
sales negotiation, timber valuation, operations planning,
tree marking, road and trail layout and supervision and/
or monitoring of operations. They will also have knowledge
of legislation and local forest conservation bylaws that may
affect your harvest activities, as well as insight into local
markets and familiarity with local loggers.
Professional forestry consultants can help you achieve
your forest management goals and ensure that the forestry
practices used in your woodlot will enhance its future
condition and value. The Ontario Professional Foresters
Association (OPFA) is responsible for the regulation of the
practice of forestry in Ontario. A list of OPFA members
who provide consulting services is available on the OPFA
website www.opfa.ca.
6

A Landowner’s Guide to Careful Logging
In addition, a listing of forestry consultants and loggers is
also available at the Ontario Woodlot Association’s Forest
Services Directory website www.ontariowoodlot.com.
Section 2.0
Guidelines for hiring consultants are similar to those
applicable to hiring loggers and are outlined in the
section below.
Hiring a logger
Many landowners decide to harvest their woodlands on
their own. Logging is physically demanding work that can
be dangerous. It requires experience and care to ensure
safe operations and to avoid damaging the woodlot.
Carefully consider all aspects of the harvest operation,
including your knowledge and skill level, time and
available resources (money and equipment). You should
also look at your stand management objectives and the
value of your timber when considering whether to log the
woodlot yourself, sell standing timber or contract logging
services.
A key step in maximizing future financial returns from the
woodlot is to minimize the damage to residual trees.
When harvesting timber, there is no substitute for a welltrained
and conscientious operator.
Remember, when selling timber, you are entering a buyer/
seller relationship. The logger is buying raw material and
reselling it. Like anyone in business, the logger needs to
buy low and sell high to make a profit. Know the value
of your timber. If necessary, hire a qualified consultant to
provide an independent appraisal. Always obtain more
than one bid to ensure that you get a fair price. Also, be
sure to consider the following when hiring or contracting
for logging services:
If you decide to
cut timber yourself,
it’s important that
you understand
the potential
hazards associated
with logging. Be
sure to maintain
your equipment
properly, wear
safety gear, carry
a first aid kit, and
most important of
all, conduct work
safely. It is strongly
recommended that
you never work
alone. Also, be
sure that family
members (or others)
know where you
are working.

is one of the
most important
determinants
in the amount
and severity of

harvesting.
✥✥The suitability of logging equipment to the woodlot site
and stand characteristics.
✥✥The level of on-site supervision during operations.
✥✥The experience of the contractor (i.e., the number of years
of experience harvesting in similar forest types).
✥✥Are all forest workers trained and certified under
the Cutter-Skidder Operator Program?
✥✥Are portions of the operation subcontracted, and
if so, are the subcontractors qualified, supervised
and insured?
Logging is dangerous, physically demanding work that requires experience
and care to ensure safe operations and to avoid damaging the woodlot.
8

A Landowner’s Guide to Careful Logging
The following guidelines are applicable whether you sell standing timber or
contract a logger to harvest your woodlot:
✥✥Ask for and check references. When possible, visit woodlots harvested by
the contractor.
✥✥Use a legally binding contract. A contract that contains terms and
conditions consistent with the objectives of your management plan
will protect both your financial interests and your investment in forest
management. See A Landowner’s Guide to Selling Standing Timber or
contact the Ontario Woodlot Association for a sample contract.
✥✥Ensure that all forest workers are trained (certified) and that the contractor
has sufficient general liability insurance and a valid Workplace Safety
Insurance Board (WSIB) clearance certificate. Obtain a WSIB clearance
certificate for confirmation that the contractor is registered and has met their
obligations.
✥✥Insist that safety equipment be worn at all times and that a first aid kit and a
spill kit are on site.
✥✥Meet with the contractor on site, prior to operations, to discuss the harvest
and clarify any misunderstandings or misconceptions.
✥✥Hire a consultant to conduct the timber sale and monitor the logging
operation, or monitor the operation yourself on a regular basis.

A Landowner’s Guide to Careful Logging
Developing a harvest plan
The harvest plan will cover six critical elements,
which are described in the following sections:
1) Stand prescriptions and tree marking;
2) Boundary marking;
3) Protection measures for sensitive features
and sites;
4) Planning access roads;
5) Harvest timing; and
6) Logging equipment.
At the onset of harvest planning, it is critically important
to walk the woodlot. This on-the-ground assessment of the
woodlot is used to develop all aspects of the harvest plan.
It is recommended that this field assessment take place in
spring or early winter when visibility in the woodlot is best.
During the reconnaissance, take note of any sensitive
features and sites (e.g., stick nests or shallow soils) and
physical characteristics that may affect logging operations
or other forest management activities (e.g., steep slopes or
rock outcrops). Mark these sites on a sketch map for use
when preparing your harvest plan.
Be sure to provide a copy of the harvest plan and sketch
map, and discuss these documents with your consultant
and/or logging contractor before logging begins.
10

A Landowner’s Guide to Careful Logging
Section 2.0
Tree marking involves the careful selection of trees for harvest. The
tree marker must assess each individual tree and give consideration
to a number of variables (e.g., regeneration, tree health, site
conditions, wildlife habitat, diversity and the overall objectives of forest
management) before a final decision is made whether to leave the tree
or mark it to be cut.
11

1) Stand prescriptions and tree marking
A Landowner’s Guide to Careful Logging
Lists of
qualified
tree markers are
usually available
through resource
agencies (see
Appendix 2).
Woodlots managed under selection or shelterwood
harvest systems should be marked in accordance to a
stand prescription prepared by a member of the Ontario
Professional Foresters Association.
The stand prescription is a key document that provides
guidance to tree markers about the number of trees to cut
or retain (e.g., species or quality) for the future timber
crop or for regeneration, as well as information about site
protection and wildlife habitat. Tree marking must meet
the intent of the stand prescription if management plan
objectives are to be realized.
The decisions made during tree marking will directly
influence the long-term economic and ecological integrity of
your woodlot. Because of this, tree marking should be done
by certified tree markers.
2) Boundary marking
Contact your local
municipality if you
are working next
to an unopened
road allowance.
Before starting operations, clearly mark all harvest
boundaries with red paint. Place these markings where
harvest operations are planned near property lines and
to identify internal harvest boundaries — areas of your
property not included in the harvest. Use evidence such
as survey markers, blazes and/or fences to assist with the
identification of property boundary lines.
Care should be taken when marking near unopened road
allowances to avoid penalties arising from cut trespasses.
Natural boundaries, such as water and associated buffers,
open fields or changes in forest cover, make excellent
natural locations for internal harvest boundaries. Ensure all
boundary marks are readily visible from all directions. Well-
12

A Landowner’s Guide to Careful Logging
marked boundary lines and a good map will help to avoid
cut trespasses and/or other property damage.
Section 2.0
Only a licensed
Ontario Land
Surveyor can
identify a property
boundary.
The Forestry Act requires mutual
consent of both owners when
harvesting boundary trees.
Inform
adjacent
property
owners of
your logging plans
and cooperatively
locate and mark
property lines.
3) Protection measures for sensitive features and sites
The harvest plan should identify, map and provide
prescriptions (direction) for stand management. It should
also protect sensitive features and sites, such as stick nests
and shallow soils in the woodlot. Mark the boundaries
of any buffer zones prior to harvesting and ensure that
they are visible from all directions. Confirm that all forest
workers are aware of the sensitive features and sites in
the woodlot and of the management requirements for the
protection of these areas. Monitor operations on a regular
schedule to ensure that marked features are not damaged.
13

A Landowner’s Guide to Careful Logging
4) Planning access roads
There are a number of factors to consider when planning
forest access. First, consider whether access road
construction is absolutely necessary. Instead of constructing
a new road, use adjacent fields, existing trails or other forest
openings. This will save money and reduce the risk of site
damage or disturbance.
When determining the type and length of road to be
constructed, consider factors such as the value of timber to
be harvested relative to road construction costs, the duration
and season of the cut, haul truck and logging equipment
requirements, safety, road maintenance costs and any water
and wetland crossing requirements. Remember, well-planned
road networks can be used for future logging operations
and for other activities in the woodlot, such as trail riding
and cross-country skiing.
Identify on the sketch map the preliminary locations of any
roads, skid trails and landings associated with the harvest
to assist in operations planning. Be sure to consider the
locations of landings, roads and skid trails for future logging
or other forest management activities.
For more information on planning and constructing access
roads, refer to Section 5.
5) Harvest timing
Choosing the right time of year to harvest can help to
minimize stand and site damage. Logging operations can
also be timed to promote natural regeneration (by timing
cuts with good seed crops or exposing mineral soil) or to
enable landowners/contractors to take advantage of good
market conditions for certain species or forest products.
14

A Landowner’s Guide to Careful Logging
Winter cutting can give excellent results. With frozen or
snow-covered soil, there are fewer access limitations in
wet areas, and rutting and soil compaction is minimized.
Visibility during operations is also increased by the
absence of leaves. This provides for safer operations
when felling and skidding. However, cutting in winter is
not without challenges, such as the potential for increased
snow-plowing costs and poor working conditions in deep
snow. Carefully weigh these factors when determining the
best time to harvest.
Section 2.0
Depending on ground and forest conditions, logging
should generally be avoided from early spring to late July.
This avoids the potential for site damage (due to wet soils)
and disruption of breeding activities of birds and other
wildlife. The risk of bark damage to residual trees from
felling and skidding abrasions is also reduced; tree bark is
highly susceptible to wounding during periods when trees
are actively growing.
For information on careful logging practices for skidding and
harvest operations, refer to Section 7 and Section 8.
Wet, low-forested
areas should be
harvested when
the ground is
frozen or during
dry periods.
15

A Landowner’s Guide to Careful Logging
6) Logging equipment
It is very important to carefully match your choice of logging
equipment with the characteristics of the woodlot and the
objectives in your management plan.
Equipment choices
also affect other
operational
considerations
(such as the width
of a road’s rightof-way)
and
construction costs.
Although it is the skill of the operator (and the care that they
take) that ultimately determines the condition of the forest
after logging, the appropriate equipment should be used
for the volume of wood to be harvested. Smaller equipment
generally leaves less of a footprint in the woodlot.
However, while small equipment may be lighter and more
maneuverable, it often requires significantly more trips to
remove a given volume of wood than larger equipment
does. This repeated travel may result in compacted soils,
excessive rutting, basal scarring to trees and root damage.
16

A Landowner’s Guide to Careful Logging
3.0 Stream Crossings
Special care is required when planning, constructing and
abandoning stream crossings. This ensures safe operations,
controls costs, and protects water quality and the aquatic
environment.
Section 3.0
Planning stream crossings
When planning stream crossings, try to minimize the
number and length of the crossings. This strategy will
reduce costs and will minimize the risk for negative
environmental impacts on water quality.
Locate potential crossing sites during the field
reconnaissance to lay out the road and trail network.
Always investigate a number of potential crossing locations
to ensure that the best possible site is selected.
When searching out potential crossing sites, look for areas
where the stream has a narrow and relatively straight
channel, a hard bottom and level or gently sloping banks.
Types of crossings
Stream-crossing structures may be temporary or permanent.
Temporary crossings that are used for a limited time reduce
the environmental impacts associated with the construction,
use and maintenance of a permanent crossing. Permanent
crossings are constructed when long-term access is
required.
The most common types of crossing structures are culverts,
bridges and fords. The type of structure installed is
determined by factors like stream size, peak water flow,
stream bed material, requirements for fish movement, other
aquatic habitat requirements, safety requirements and cost.
Stream crossings
must be in
compliance
with the federal
Fisheries
Act and the
Conservation
Authorities Act.
The Fisheries Act
makes it illegal to
harmfully alter,
disrupt or destroy
fish habitat.
Before starting
any crossing,
contact your local
conservation
authority (CA)
or the Ontario
Ministry of Naturl
Resources (OMNR)
office (if there
is no local CA)
for advice and
permits.
17

A Landowner’s Guide to Careful Logging
Crossing structures
Talk to
a local
forestry consultant
or CA for
assistance in
determining the
type of crossing
or structure that is
most appropriate
to your
circumstances.
Of all forest management activities, the installation, use and
removal of water and wetland crossings have the greatest
potential to impact water quality. Specific guidance on
locating and constructing water crossings is provided in the
sections below.
Rip rap or cobbles are larger stones used to stabilize
culverts and prevent water from undercutting the culvert.
Careful logging practices for locating and constructing
stream crossings
Regardless of the type of crossing or structure used, adopt
the following procedures:
✥✥Locate crossings where the soil is stable and not easily
eroded.
18

A Landowner’s Guide to Careful Logging
✥✥Keep the crossing as short as possible, while ensuring
suitable abutment on each stream bank.
✥✥Install the crossing at a right angle to the stream channel.
✥✥Do not obstruct water flow or fish movement during the
construction.
✥✥Construct road approaches to crossing structures using
fill instead of grubbing to minimize the potential for
erosion. Ensure that the “no-grub zone” is at least the
width of the riparian buffer zone (see Section 4). Keep
the approaches straight, level or gently sloping. Reduce
erosion or sedimentation by applying crushed rock or
gravel to the approach.
✥✥Grade any exposed soil to a stable angle and protect it
from erosion by seeding and/or applying mulch.
✥✥Use
water bars, dips, cross drains or other diversion
structures to reduce erosion near the crossing site. (See
the sections below for guidelines on installing and
removing these structures.)
✥✥Do not operate equipment in the stream during crossing
installation or removal.
✥✥Inspect crossings periodically for structural safety. Ensure
that fish passage and water flow are not obstructed by
blockages.
✥✥Avoid construction work during wet weather or when the
soil is saturated.
✥✥Use
rip rap to stabilize culverts and prevent undercutting
and erosion.
Section 3.0
19

A Landowner’s Guide to Careful Logging
Fords are the least expensive type of stream crossing.
They should only be used during periods of low water
flow and where the stream bed is comprised of stable
material (i.e., rock or gravel).
Fords
A ford is the most basic and least expensive type of stream
crossing. A ford uses the stream bed as part of the road or
access trail.
CLPs for locating and using fords
Adopt the following careful logging practices:
✥✥Locate ford crossings only where stream banks are
low and gently sloping and where the stream bed is
comprised of stable material (i.e., gravel or rock), with
good load-bearing capacity.
✥✥Fish spawning beds often occur at or near good ford
crossings sites. Do not ford streams at these locations.
20

A Landowner’s Guide to Careful Logging
✥✥Where the stream bed is less stable, use rocks, logs
or man-made materials (e.g., rubber mats) to support
equipment.
✥✥Construct and use fords only during periods of low water
flow (i.e., when the water is less than 0.3 m deep).
✥✥Keep equipment (that will use the ford) clean and well
maintained.
✥✥Protect approaches to the ford with clean gravel, brush
mats or other temporary surfacing materials to minimize
the amount of mud and debris, which may be dragged
into the water by the equipment.
✥✥When abandoning the ford, ensure that all material used
to stabilize the stream bed is removed from the water.
Additional information and guidelines for ford crossings
are available on the Department of Fisheries and Oceans
(DFO) website http://www.dfo-mpo.gc.ca/regions/
central/index-eng.htm.
Section 3.0
Obtain advice
from your local
CA before
placing any
materials in a
stream. Make
sure that materials
are clean, will
not erode and
are non-toxic to
aquatic life.
21

A Landowner’s Guide to Careful Logging
Bridges
Bridges may be temporary or permanent. The cost of
installation and maintenance is directly related to the length
of time the structure will be used, the span it crosses and the
load it is intended to carry.
Using a bridge is the most effective means to protect water
quality. Bridges span the water, reducing the potential
for sedimentation during construction, maintenance and
abandonment.
All bridge designs
(portable and
permanent),
including
abutments, need
to be approved
by a professional
engineer.
Portable bridges are becoming increasingly popular
with landowners and loggers as they offer several cost
advantages. While initially more expensive than other
crossing structures, portable bridges can be reused and
are easier to install than traditional structures.
22

A Landowner’s Guide to Careful Logging
CLPs for installing bridges
The following careful logging practices are recommended
for installing bridges:
Section 3.0
✥✥Set bridge abutments well back from the edge of the
stream.
✥✥Construct the bridge higher than the approaching road
or trail to prevent surface runoff from draining onto the
crossing structure.
✥✥Use solid decking to prevent debris from falling through
the deck into the watercourse.
✥✥Where there is a risk of flooding, anchor temporary
bridge structures.
Culverts
Culverts can be installed as either temporary or permanent
structures to cross a permanent or intermittent stream.
CLPs for installing culverts
Use the following careful logging practices to protect water
quality when installing culverts:
✥✥Size the culvert to handle peak water flow. Seek
the advice of a forestry consultant to assist you in
determining the appropriate culvert size.
✥✥Install the culvert during a period of low water flow. This
will reduce the impact on water quality and the potential
for disrupting fish movement during culvert installation.
✥✥Ensure that any fill material used does not extend beyond
the end of the culvert.
✥✥Install the culvert on compacted granular material. Ensure
that at least ten percent of the pipe diameter of the

the movement of fish through the pipe.
✥✥Use rip rap around the culvert inlet to prevent water from
eroding and undercutting the pipe.
Culverts must be set into the stream bed (bottom

environmental damage.
CLPs for abandoning a crossing
Landowners may wish to maintain water crossings
permanently to facilitate recreational activities or future
forest management operations in the woodlot. In other
circumstances, it may be advisable to remove the crossing
to prevent possible negative environmental impacts, arising
from the degradation of the crossing. Removing a crossing

A Landowner’s Guide to Careful Logging
also helps prevent trespassing. A landowner may also
want to use the structure (e.g., portable bridge) at another
location.
Section 3.0
In instances where a decision is made to remove a
crossing, it is important to ensure that the crossing is
properly removed and that the site is left in a suitable
condition to prevent water quality problems associated with
erosion and sedimentation. Use the following practices to
properly remove (close) a stream crossing:
✥✥Remove the structure and all materials used in its
construction below the high-water mark.
✥✥Ensure that water flow on roads and trails is dispersed
onto stable areas of undisturbed forest floor, away from
the stream.
✥✥Use brush, hay, grass or other materials to stabilize any
exposed soil within the riparian buffer zone.
✥✥Monitor the crossing site periodically after abandonment.
If erosion is occurring, take appropriate action, such as
seeding or applying mulch to exposed soils, regrading
and smoothing slopes to stable angles or applying
gravel or brush mats on crossing approaches.

4.0 Working Around Water
In this guide, “water” includes lakes, rivers, streams,
intermittent streams, open wetlands, woodland pools,
seeps and agricultural drains. Special care and attention
is required when cutting timber adjacent to water as these
areas (known as riparian areas), are particularly sensitive
to site disturbance. This section of the guide provides CLPs
for harvesting near open water and wetlands; Section 8
provides CLPs for harvesting in treed swamps.
Harvesting activities in riparian areas can take two
approaches: riparian areas may be left and not harvested,
or modified cutting may occur. The modified approach
establishes buffer zones allowing some trees to be
harvested while protecting and enhancing the ecological
functions and habitats of riparian areas.
Section 4.0
Care
should
be taken
when
working in treed
swamps (e.g.,
stands of silver
maple, cedar,
black ash). Refer
to Section 8 for
more information.
When working in or around wetlands
and water, know which laws (e.g.,
Fisheries Act, Conservation
Authorities Act) apply to your situation. Permits
and/or timing restrictions may also apply. Contact
your local CA (or OMNR office if there is no local CA)
for information and guidance.
Woodland pools are temporary pools of water that
generally appear in the spring (vernal pools) from
snowmelt or heavy rains; they sometimes appear in the
fall of the year (autumnal pools).
27

A Landowner’s Guide to Careful Logging
Establishing buffer zones
Seek the
advice
of a forestry
consultant or CA
when establishing
buffer zones.
The decision whether to establish a riparian buffer resides
with the landowner. This decision should be made after
due consideration of existing legislation and recognition of
the ecological functions of riparian areas (wildlife habitat,
maintenance of water quality and quantity, wildlife travel
corridors, etc.). Also, the impacts of the planned harvesting
system and physical site conditions (e.g., soil type, slope,
type and size of the water body, sensitivity of the fishery,
flow characteristics, etc.) should be considered.

Limiting the impact to the bank of the watercourse, forest floor, trees and
other vegetation within the buffer area will help maintain the health of the
riparian area and the water quality. The width of the buffer area along the
watercourse is determined by the slope of the bank (i.e., steeper slopes [left]
have a wider buffer area; gentler slopes [right] have a narrower buffer).
28

A Landowner’s Guide to Careful Logging
It is common practice in forestry to establish a buffer with
two distinct zones.
1. Immediately adjacent to the water’s edge, a nodisturbance
zone is maintained where the forest floor
and vegetation are left undisturbed.
Section 4.0
2. Outside of the no-disturbance zone, a larger buffer area
is maintained where cutting is modified and equipment
access is limited. (Refer to CLPs for Working around
water and open wetlands and Maintaining forest cover
in buffers for guidance).
Together, these zones function to reduce the potential for
negative environmental impacts on the riparian area, on
the water and on watercourses (e.g., lake, stream, open
wetland, spring, etc.).
The water flowing from a seep is true groundwater, not surface
runoff, and its temperature will generally remain relatively constant
year-round. They are typically found along lower slopes and
are very susceptible to soil compaction and rutting from logging
equipment or ATVs.
29

A Landowner’s Guide to Careful Logging
CLPs for establishing buffer zones around water and
open wetlands
Adopting the following CLPs will assist in protecting water
quality and riparian and aquatic habitats.
✥✥For lakes, rivers and streams, adopt the buffer zone
guidelines presented in Table 1. Within the buffer,
immediately adjacent to the water’s edge, maintain a
minimum 3-m no-disturbance zone. In the remainder of the
buffer, modify harvest operations by limiting equipment
access and maintaining a minimum canopy closure. Buffer
zones should be measured from the high-water mark.
Table 1: Recommended Buffer Zone
Widths Based on Slope
(degrees) for Watercourses
Slope (degrees)
Buffer Zone
Width (metres)
0-8.5 30 m
8.6-16.7 50 m
16.8-24.2 70 m
>24.2 90 m
✥✥For open wetlands (i.e., bogs, fens and marshes),
woodland pools, agricultural drains and intermittent
streams, adopt a 15-m buffer zone. The width of the
buffer should be measured from the high-water mark.
Within the buffer, immediately adjacent to the feature’s
edge, maintain a minimum 3-m no-disturbance zone. In
the remainder of the buffer, modify harvest operations by
limiting equipment access and by maintaining a minimum
canopy closure.
30

A Landowner’s Guide to Careful Logging
✥✥To protect seeps, adopt a minimum 3-m no-disturbance
zone of undisturbed vegetation adjacent to the feature.
Section 4.0
Streams have defined channels and banks and may flow
year-round (perennial) or only during part of the year
(intermittent).
CLPs for working around water and
open wetlands
Timber harvesting can occur in riparian buffer zones with
little negative environmental impact, provided that some
basic guidelines are adhered to and that operations are
conducted with care.
Use the following CLPs to protect water and soil quality
when logging in a riparian area:
✥✥Log only during periods when soils are dry or frozen to
avoid rutting and erosion.
✥✥Limit machine travel in the buffer to minimize soil
disturbance and erosion. When feasible, use cables and
a winch to extract timber.
31

A Landowner’s Guide to Careful Logging
✥✥When cutting, keep felled trees and slash out of the
water. Avoid damaging the shoreline or exposing soils,
which may erode into the water.
✥✥Avoid locating roads and landings in the buffer zone
(except to access a water crossing).
✥✥Do not allow ditches or other water diversion structures
to drain directly into the wetland or watercourse. Divert
runoff onto undisturbed areas of the forest floor.
✥✥Properly close all roads and trails leading into the buffer
zone (see Section 7).
✥✥Do not fuel, service or wash equipment near water.
Maintaining forest cover in buffers
It is important to maintain adequate tree cover within the
buffer zone. Cutting too many trees can lead to dramatic
changes in the composition and structure of the forest.
This may adversely affect the quality and quantity of water
entering the riparian area, resulting in sediment entering the
aquatic feature and altering the hydrologic function of the
riparian area.
Trees also deposit leaves, twigs and other organic material
and debris into the water, providing habitat, cover and food
for aquatic life. Reductions in the amount of these materials
reaching the water can alter food supplies and habitats for
fish and other aquatic life.
Depending on the silvicultural prescription, it is
recommended that a minimum of 50 to 70 percent canopy
closure (trees greater than ten m in height) be maintained
within the modified area of the buffer zone.

CLPs for wetland crossings
A Landowner’s Guide to Careful Logging
Cross wetlands only when absolutely necessary and only
after assessing the feasibility of all other options.
Where crossings are necessary, exercise good judgment
and care when locating and constructing crossings. Use the
following careful logging practices to plan and construct
wetland crossings:
✥✥Schedule harvest operations to cross wetlands when the
ground is frozen.
✥✥The crossing installation should not restrict surface or
subsurface water movement in the wetland.
✥✥Use water-diversion structures to divert water off trails and
roads, so they do not drain directly into the wetland.
✥✥Monitor the crossing site periodically after abandonment.
If erosion is occurring, take appropriate action.

A Landowner’s Guide to Careful Logging
5.0 Access Roads
The factors that determine the type and number of roads
required for harvesting operations include: topography,
stand conditions, use of adjacent land, silvicultural system
and the type of logging equipment to be used.
Section 5.0
Poorly planned and built forest access roads can create the
most lasting disturbance effect, associated with logging, in
the woodlot.
Improper
construction
practices can
result in erosion
problems,
environmental
degradation
and higher road

costs.
35

A Landowner’s Guide to Careful Logging
Types of access roads
Access roads may be temporary or permanent. Temporary
roads are least expensive to build. Permanent roads are
built to a higher standard for year-round use and are much
more expensive to construct and maintain.
Woodlot owners and loggers can save money and
reduce the potential for negative environmental impacts
by using old access roads and trails in the woodlot. Walk
these roads and trails to determine: 1) if their layout can
meet current needs; and 2) if their locations comply with
today’s more rigid environmental requirements with respect
to crossing wetlands and other sensitive areas. Also, as
a cost savings and environmental protection measure,
consider using agricultural fields adjacent to the woodlot as
substitutes for roads, trails and landings.
If new roads must be built, save money and protect the
environment by building the shortest road possible, with the
fewest number of water crossings. However, recognize that
longer skidding distances increase the potential for stand
and site damage during operations. This can also increase
the cost of logging, and reduce revenues for the landowner.
Be sure to budget adequate funds for road construction and
maintenance. Roads that are well- built and maintained will
reduce logging costs by:
✥✥allowing trucks to haul heavier loads for longer periods of
time (i.e., all seasons);
✥✥allowing trucks to safely travel faster, reducing haul times
and increasing efficiencies; and
✥✥reducing road and vehicle maintenance costs associated
with travel wear.

Shaping the road (crown) will help move water off
the road surface. This will keep the surface dry and
structurally sound, prolonging periods of use and the
service life of the road.
CLPs for access road construction
Walk the proposed road and trail network with your
consultant and logging contractor before construction starts.
During this field assessment, do the following:
✥✥Take note of any old roads, trails or natural openings
that could be incorporated into the road network or used
as landings.
✥✥Keep in mind the logging equipment and trucking
requirements of the operation.
✥✥Locate and mark control points, such as landings, steep
slopes or rock outcrops.
✥✥ Try to locate roads on well-drained soils and gentle slopes.
✥✥Ensure that road and trail locations avoid unstable
slopes/soils and areas where grades are in excess of
ten percent.
37

A Landowner’s Guide to Careful Logging
✥✥Ensure that all potential water or wetland crossing
locations meet environmental protection criteria. (See
Section 3 and Section 4 for guidance.)
✥✥Identify all construction or erosion control requirements
(i.e., the need for cut and fill or drainage structures).

installation procedures and requirements are provided in
the illustration.
Consider the following careful logging practices when
planning and building forest access roads:
✥✥Permanent roads should be planned and constructed
far in advance of being used. As a general rule, roads
should be built, then allowed to season for a winter and
spring prior to use.
✥✥Locate temporary winter roads in lowland areas and
avoid hills.
38

A Landowner’s Guide to Careful Logging
✥✥Locate temporary summer roads on sites with high loadbearing
capacity (i.e., on coarse textured soils).
✥✥Construct roads with a slight slope (one to two percent).
Where grades are steeper, use diversions to move water
off the road surface.
✥✥Shape the road with a crown, an inslope or an outslope
to drain water off the road.
✥✥Construct the road and ditches in one operation.
✥✥Keep excavated material out of ditches and ensure
that it will not erode into watercourses. Use temporary
sediment barriers as required to minimize erosion.
✥✥Stabilize permanent road surfaces with gravel, crushed
stone or other material to help shed water and increase
the road’s load-bearing capacity.
✥✥Compact and shape fill to reduce erosion, minimize
settling and increase load-bearing capacity.
✥✥Corduroy
soft areas on temporary roads with a brush
mat or unmerchantable wood to prevent rutting, ponding
and erosion.
✥✥Keep road widths to a minimum.
✥✥When crossing agricultural fields, beware of field tile.
When necessary, cross fields parallel to the direction of
the tile. Also, following the edge of the field will avoid
most of the drainage tiles.

Ditches carry runoff from the road surface and uphill areas. Ditches that are
U-shaped (right) or flat bottomed (left) are preferred over steeper V-shaped
ditches because they are more stable and promote slower water flow. It is
important to keep ditches clear of debris to protect the road from flooding
and erosion.
40

A Landowner’s Guide to Careful Logging
Water diversions and drainage structures
Water diversions (water bars, broad-based dips, berms,
ditches and cross-drain culverts) are used to divert water
away from the road surface and to control water flow
along the surface of a road. Install sufficient water
diversions to move water off the road. This will protect the
road surface and structure. Construct the diversions so that
they divert water to undisturbed areas of the forest floor,
rather than directly into water or wetlands. Monitor the
diversions periodically to remove blockages and ensure
that they are functioning properly.
Section 5.0

flows onto a filter area of undisturbed forest floor, well
away from the riparian area or watercourse requiring
protection.
There are a number of erosion control methods that can
be adopted to control erosion and sedimentation during
harvest operations. Illustrations and guidelines for various
water diversion structures and erosion control techniques
are presented in this Section and in Section 7.

A Landowner’s Guide to Careful Logging
Sedimentation controls
When constructing water crossings or diversions, it is
important to minimize the risk of sediment getting into water
or filter areas. Techniques and guidelines for sedimentation
control are illustrated in the photographs below.
Silt fences can be used to minimize sedimentation during
crossings or construction of water diversions. Ensure that
the fencing material is secured to stakes and that fencing
fabric is buried to a depth of at least ten cm on the
upslope of the fenceline.
42

A Landowner’s Guide to Careful Logging
Section 5.0
Hay bales can be used as a temporary sediment barrier
to prevent newly exposed soil from entering water or
buffer areas. The photo above shows a barrier made of
straw bales and a silt fence.
CLPs for road maintenance
Proper maintenance will protect your road and water
quality. Use the following CLPs to maintain road surfaces
and to extend the service life of your road:
✥✥Avoid using roads during periods of prolonged rain or
thawing.
✥✥Regularly inspect and clear blocked ditches and
drainage structures. Replace damaged or failing culverts.
✥✥Grade roads to maintain their surface shape. Try not to
mound surface material along the road’s edge because
this will cause ponding and/or channel water onto the
road surface.
✥✥Clear vegetation along a road’s right-of-way for safety
and to ensure proper drying of the right-of-way.
43

A Landowner’s Guide to Careful Logging
It is important to monitor water crossings to prevent
possible negative environmental impacts, arising from the
degradation of the crossing.
CLPs for road closures and retirements
Landowners may wish to maintain roads permanently to
facilitate recreational activities or future forest management
operations in the woodlot. Alternatively, landowners may
elect to close or retire roads in the woodlot to prevent
negative environmental impacts, such as erosion and
sedimentation. This will also help to reduce trespassing and
costs associated with road maintenance.
Abandoned and closed roads can contribute significantly
to erosion and to sedimentation problems when they are
not retired correctly. Most erosion problems occur within
two years of the road closure, prior to the road naturally
revegetating.
Implementing proper road abandonment procedures will
help protect the road surface and drainage structures for
future use.
44

A Landowner’s Guide to Careful Logging
Adopt the following careful logging practices when
abandoning or retiring access roads:
✥✥Remove all temporary drainage and stream crossings.
✥✥Ensure that crossing materials are not left in the stream
and that the stream banks are stable.
✥✥Shape road surfaces as necessary to maintain surface
drainage.
✥✥Construct water bars or other water diversions where
surface runoff or cross drainage may cause erosion or
sedimentation.
✥✥Ensure that permanent drainage structures are functional
and free of debris. Monitor these periodically.
✥✥If necessary, construct berms or other barriers to restrict
road traffic in the woodlot. Any berms or barriers
constructed for this purpose should be built in a manner
that does not pose a safety hazard.
✥✥Stabilize and seed areas where the soil is exposed.

Landings are the hub of a logging operation. Good planning and
proper construction of the landing can improve logging productivity.

A Landowner’s Guide to Careful Logging
6.0 Log Landings
Log landings are cleared areas where wood is piled,
sorted or stored before being loaded onto trucks.
Section 6.0
Special care must be taken when planning, constructing
and using landings to ensure safe operations and to
minimize disturbance to the residual stand and the
environment. If landings are not located properly or are
poorly constructed, large areas of soil may be exposed or
disturbed, leading to erosion and sedimentation problems.
Hazardous materials, such as fuel and lubricants, are often
stored at landings. Routine machine maintenance and
equipment repairs also take place at these sites. Care must
be taken to ensure accidental spills do not occur.
Proper planning will ensure that the size and location of
the landing is compatible with the harvesting system (e.g.,
harvest hauling and loading equipment) and environmental
requirements in the woodlot (e.g., landings should not be
located near water).
Upon completion of operations, landings should be
decommissioned. These sites can be reforested or seeded
to reduce erosion. They can also be left as an open area
for wildlife or future logging operations.
To help reduce the loss of productive land and wildlife
habitat, try to minimize the size and number of landings.
The number and spacing of landings is mainly a function
of local site conditions, access roads and logging/hauling
equipment requirements.
Depending on operational requirements, it may be feasible
to pile wood on the road right-of-way, rather than to
construct a new landing. If new landings are required,
47

A Landowner’s Guide to Careful Logging
Check
with
your local
municipality or
neighbour for
permission to use
open lands, such
as fields and road
allowances, for
landings.
consider locating them in adjacent agricultural fields or in
natural woodlot openings. Whenever possible, use landings
from past harvesting operations.
Identify landing locations before road construction or
harvesting begins. Investigate a number of potential
locations to ensure the best possible site(s) for the operation
is selected.
CLPs for constructing and using landings
The following careful logging practices should be
considered when constructing and using landings:
✥✥Landings should be located by the logger and reviewed
and approved by the landowner before operations begin.
✥✥Landing locations should be clearly marked prior to
operations.
✥✥Construct landings well away from water, buffer areas
and other sensitive sites. Select locations with firm, welldrained
soils. If required, use temporary water barriers
(e.g., hay bales) to limit erosion when constructing or
using the landing.
✥✥Lay out skid trails and roads so that water cannot flow
into or out of the landing. Use water bars, berms or other
structures to prevent water from entering or exiting the
landing. (Refer to Section 5 and Section 7 for information
on water diversions).
✥✥Minimize soil disturbance when constructing landings.
Simply clearing vegetation, rather than bulldozing down
to mineral soil, will aid in the rehabilitation of the site after
operations.
✥✥Maintain the landing surface to keep water from ponding
or channeling.
48

A Landowner’s Guide to Careful Logging
✥✥After significant rainfall, allow the landing to dry
before using it.
✥✥Minimize the amount of wood waste at the landing
and leave as much woody material as possible at
the felling site.
✥✥Keep a spill kit on site to soak up any lubricant spills
or leaks. (See Section 8).
✥✥Keep the landing clean and clear of garbage and
debris.
Section 5.0
CLPs for landing abandonment
Adopt the following careful logging practices to stabilize
the landing after operations:
✥✥Stabilize the site and prevent erosion by allowing the
landing to regenerate naturally or by applying seed,
mulch or other materials.
✥✥Plant grasses or shrubs to revegetate the landing, with a
view to future use, or to provide wildlife food and cover.
It may be necessary to prepare the landing site for
planting to ensure an adequate seed bed.
✥✥Monitor the landing site periodically for erosion
problems and maintain as necessary.
✥✥Landings in agricultural fields should be cleared of all
logging debris (e.g., blading off or using debris as
firewood) at the end of harvest operations.
Landings that
are seeded and
maintained as
open areas can
be reused with
minimal cost and
effort. Seeded

A Landowner’s Guide to Careful Logging
7.0 Skid Trails
Skid trails are used to move cut timber from the stump to
the landing. Repeated trips are often made on the same
skid trail; loggers must use care and skill to avoid rutting,
erosion and damage to residual trees in the woodlot.
Section 7.0
Many of the planning principles and operational practices for
forest access are applicable to planning and using skid trails.
CLPs for planning and locating skid trails
Planning skid trails is an important task and requires an
understanding of the silvicultural objectives associated with
the harvest. It is also important to have an understanding
of the limitations and capabilities of the harvest equipment
and to be familiar with the terrain and soil conditions of
the woodlot.
When planning skid trails, keep in mind that the amount
of logging damage is directly proportional to the number
of trails. A skilled logger can minimize the number of trails
and significantly reduce the potential for site and stand
damage.
Landowners
should require
the logger to
lay out the main
skid trails before
cutting begins.
All trail locations
should be subject
to the landowner’s
review and
approval.
Proper skid trail
layout improves
the efficiency of the
logging operation,
reduces the risk
of damage to the
residual stand
and soil and
minimizes the loss
of productive forest
in the woodlot.
51

A Landowner’s Guide to Careful Logging
Adopt the following CLPs when planning and laying out
skid trails:
✥✥Whenever practical, locate trails outside of the woodlot
or use existing trails when they provide good access to
the harvest area.
✥✥Lay out skid trails to minimize the total number of trails,
number of water crossings and skidding distances. If
possible, place trails on the top of topographic contours.
This will prevent erosion problems and provide safer
operating conditions.
skid trail
water bars
slash to disperse flow
Install water bars to move water off the skid trail or
access road. They are cost effective, and if properly
placed and constructed, will provide adequate cross
drainage and surface drainage. Construct dips deep
enough to provide adequate drainage and wide
enough to provide for the safe passage of vehicles and
equipment. Placing gravel or crushed stone on the dip
and mound is recommended to improve stability.
52

A Landowner’s Guide to Careful Logging
✥✥Ensure that the location of main skid trails tie into any
proposed or existing log landings and access roads.
✥✥Before cutting begins, flag main trails and identify any
areas where additional skid trails may be required or
where skidding may be restricted or problematic.
✥✥Lay out new trails to access the harvest area by the most
direct route.
✥✥Be sure tree marking is complete before laying out skid
trails in the field. This will ensure that the skidder will
access the cut in an efficient manner and minimize the
potential for stand damage (by limiting machine travel
through areas of unmarked timber).
✥✥A good rule of thumb is to space skid trails at least 30 m
apart. This spacing permits the winching of trees and
reduces the amount of machine travel needed.
✥✥Confine skid trails to where trees have been designated
for harvest.
✥✥Keep main trails straight or gently curving.
✥✥Locate secondary and tertiary trails so they intersect main
trails at angles of less than 45 degrees.
✥✥Keep all trail widths to a practical minimum to avoid
unnecessary timber losses, recognizing that trails that are
too narrow will increase the potential for residual tree
damage.
✥✥Avoid steep grades. This will reduce site damage.
✥✥When trail slopes are greater than five percent, plan to
install drainage structures or water diversions and use
soil stabilization practices (i.e., brush mats) to reduce
erosion and runoff.
Section 7.0

Natural humps in the terrain (skid humps) can be used to help divert water
from skid trails. The hump forces water out of the trail. The placement of rocks
or slash at the lower end of the hump will assist in dispersing water onto the
forest floor.
✥✥Use low-value trees or trees that are marked for harvest as
bumper trees. Bumper trees will cushion standing timber
and regeneration from damage by skid loads that track
off the centre of the trail.
✥✥To avoid any misunderstandings about where machine
traffic should not occur, it is recommended that
landowners discuss skid trail locations with their forestry
consultant and logger before harvesting begins.
CLPs for skidding operations
Refer to Section 8 for recommended careful logging
practices for skidding.

and/or repair all trails as necessary.
✥✥Install and/or maintain water bars or berms as
necessary to control for erosion.
✥✥Seed any disturbed areas that may be vulnerable to
erosion. Allow other areas to regenerate naturally.
Landowners may elect to close or retire roads and/or trails after the
harvest operations are completed. When retiring a road or trail areas
of exposed soil should be stabilized and seeded to minimize erosion and
sedimentation problems.

A Landowner’s Guide to Careful Logging
8.0 Logging Operations
Although some damage to the site and residual trees
during logging is inevitable, it is possible, through careful
logging practices, to minimize the amount of damage in
your woodlot. Proper planning and care during operations
can help minimize damage to soil, the residual stand and
water quality.
Care and due diligence during operations also reduces
safety risks and will leave the woodlot in better condition
for other uses after logging is finished.
Harvest-related legislation in Ontario
Legislation affecting timber harvests on private land is
summarized in Appendix 1. Landowners and loggers
should be aware of all applicable legislation and
regulations prior to starting logging operations. Legislation
and regulations may include, but are not limited to, the
following: Fisheries Act, local forest conservation bylaws,
Environmental Protection Act, Occupational Health and
Safety Act, Endangered Species Act, Species at Risk Act,
Migratory Birds Convention Act, Forest Fire Prevention Act
and the Conservation Authorities Act.
Recommended CLPs for logging operations
There is no substitute for carefully planned and conducted
operations. Careful planning will help maximize safety,
protect the residual stand, protect the environment and
reduce costs. Before any cutting starts, plan the harvest
according to the recommendations provided in Section 2.
If you plan to contract the logging or sell standing timber,
meet with the logger on site before cutting starts. This
will give you an opportunity to review your expectations

with the logger and discuss any issues or logging-related
concerns (e.g., damage guidelines, no-cut zones, etc.).
Good communication before and during operations will
lead to better results.
Once work starts, monitor operations on a regular basis for
site and stand damage and adherence to the harvest plan
and management plan. Monitoring should be done with the
logging contractor.
Logging damage
Improper logging and skidding techniques can result in
lasting damage to the stand and site. After logging, a
minimum of 90 percent of the good-quality, residual stems
should be free of major damage. Skilled loggers and
operators can achieve a higher damage-free standard
(e.g., 95 percent). Appendix 3 provides information
and guidelines on how to conduct a logging damage
assessment and determine the level of damage to residual
trees in the woodlot.

CLPs for felling timber
Professional training and competence is the key to reducing
damage in the woodlot.
Section 8.0
Loggers should use the following careful logging practices
when felling timber:
✥✥At the start of operations, remove hazard trees as a
preliminary safety precaution.
✥✥Use directional felling techniques to fell trees away from
trees you wish to keep.
✥✥Limb and top trees where they fall. This practice reduces
residual damage during skidding, and the slash provides
a source of nutrients as the materials decompose.
✥✥Leave unmerchantable slash in the harvest area. This
will help to maintain soil productivity, scatter seed for
regeneration and provide cover and food for wildlife.
✥✥Minimize the amount of debris and slash arising from
operations by using all marketable wood. Cut stumps as
low to the ground as possible.
✥✥Remove severely damaged trees in the understorey to
promote safety and woodlot health.
✥✥Cutting should start at the back of the harvest block and
proceed in an orderly fashion toward the landing.
✥✥Trees should be felled, aligned with the direction of
skidding (i.e., butts toward the skid trail and at angles
no greater than 45 degrees).
✥✥Ensure good communication between the cutter and
skidder operator. This is a must for productive skidding
and to ensure that all felled trees are utilized.
59

A Landowner’s Guide to Careful Logging
An excess of skid trails can damage residual trees and
reduce the growth potential and the future value of
timber. Too many trails also diminish aesthetics and may
compromise the ecological functions of the woodlot.
CLPs for skidding operations
Loggers should use the following careful logging practices
when skidding timber:
✥✥Use low-value trees, stumps or boulders as bumpers to
protect the residual crop.
✥✥Remove large side branches from cut trees before
skidding.
60

A Landowner’s Guide to Careful Logging
Section 8.0
Directional felling (using a wedge) will fell trees away
from regeneration and other valuable trees. It will also
assist in aligning trees for skidding and will reduce
swing damage to residual trees.
✥✥Avoid unnecessary skidder travel within the stand and
buffer zones by using a winch to collect felled trees. Use
a winch to pull down lodged trees or to retrieve trees on
steep slopes.
✥✥Back the skidder toward the load on side trails, rather
than circling around the load from behind to pick up
wood.
✥✥Avoid skidding when the soil is saturated. During periods
of prolonged rain, stop operations until the soil dries.
61

A Landowner’s Guide to Careful Logging
Skidding during the early spring or late fall, when there is excessive
moisture in the ground, can do irreparable damage to your woodlot.
When harvesting
in a treed swamp
a permit may be
required under
the Conservation
Authorities Act.
Contact your
local CA for more
information.
✥✥Avoid skidding through wet spots.
✥✥For winter operations, mark stream channels and existing
culvert locations before snowfall.
✥✥Use slash or brush mats on skid trails to minimize soil
compaction and rutting and to disperse water on trails.
✥✥To reduce equipment wear, extend machine life and
reduce physical site damage, do not overload equipment.
✥✥The winch cables on the skidder should have a minimum
of 20–25 m (75 ft.) of main line.
CLPs for harvesting treed swamps and forested lowlands
Treed swamps and forested lowlands are sensitive
ecosystems because of their high- or potentially high-water
tables, shallow rooting depths and poor drainage. A rise
62

A Landowner’s Guide to Careful Logging
in the water table can occur after logging, which may
negatively affect the residual stand (e.g., cause tree
mortality or decline, windthrow, etc.).
Section 8.0
The decision to log these sites should be carefully
evaluated as these areas may provide important
hydrological functions in the woodlot and important fish or
wildlife habitat.
Should a decision be made to harvest, adopt the following
CLPs to minimize site damage:
✥✥Restrict timber harvesting to periods when the ground is
frozen or dry.
✥✥Contain skid trails to as small an area as possible and
minimize the number of trails.
✥✥Use low-pressure, high-flotation tires or wide tracks when
possible so that excessive damage to the residual stand
will not occur.
✥✥Use logging slash, mats or other techniques to reduce
soil compaction and rutting.
✥✥Keep skidder loads light when rutting is evident.
✥ ✥Maintain a minimum of 70 percent canopy (closure of
trees greater than ten m in height) to avoid changes to
the water table.
Seek
the
advice
of a
forestry consultant
or your local
CA to determine
whether logging
in a treed swamp
or lowland is
ecologically
appropriate.
63

A Landowner’s Guide to Careful Logging
Harvesting when
the ground is
frozen and
placing slash on
skid trails will
help minimize
soil disturbance.
CLPs for woodlot aesthetics
Make sure that
all terms and
conditions are
clear at the time
of the timber
sale. There may
be additional
costs associated
with some
measures needed
to improve the
aesthetics of the
harvest site.
Landowners can take several steps to ensure that logging
operations maintain or enhance aesthetic values and wildlife
habitat in their woodlots. To soften the visual impact of the
cut, adopt the careful logging practices outlined below:
✥✥Lop tops and slash down to 1m or less in height in high
visibility areas of the woodlot.
✥✥Leave primary skid trails free of debris.
✥✥Harvest highly damaged trees (i.e., broken tops,
excessive bark loss, leaners). Leave other damaged trees
for wildlife.
CLPs for wildlife habitat protection or enhancement
Small woodlots are habitat for many species of plants and
animals. Harvesting operations that are well-planned and
-conducted can result in greater diversity of habitat through
a better mix of older and younger trees and the retention of
a diversity of tree species. This will result in your woodlot
being more attractive to many wildlife species.
64

A Landowner’s Guide to Careful Logging
Wildlife management objectives are typically identified
in the woodlot management plan and in the stand
management prescription. On the ground, wildlife
values are protected by the proper delivery of
tree-marking guidelines and/or the establishment of
buffers or no-cut zones.
Section 8.0
Some habitats may be enhanced by cutting strategies that
promote the regeneration of species that provide food
or cover. Slash from the logging operation may also be
an important source of food and cover for many wildlife
species (e.g., food for white-tailed deer during winter).
Stick nests are
an important
feature for
wildlife
because they
may be used
repeatedly.
65

A Landowner’s Guide to Careful Logging
The
Ontario
Ministry of
Natural Resources’
website features
an extensive
series of wildlife
management
guidelines and a
list of endangered
species (see
Appendix 2).
Cavity trees are
living, dying or
dead trees that
contain one or
more holes or
cavities. Cavity
trees are used
by wildlife for
a variety of
purposes: nesting
and raising young,
denning, roosting,
resting, feeding,
caching food,
escaping predators
and hibernating.
Some wildlife species are highly sensitive to disturbance
and require the establishment of buffers or timing restrictions
during the nesting and breeding season to ensure breeding
success. It may also be important to avoid logging in or
around sensitive habitats. Landowners should be aware of
vulnerable wildlife living in their woodlot.
To protect and/or enhance the wildlife potential of the
woodlot, consider adopting the following CLPs:
✥✥Try not to schedule harvests during the critical breeding/
nesting season of raptors and songbirds (generally from
early spring to late July).
✥✥To provide critical habitat for a number of wildlife species,
retain a minimum of six quality cavity trees, eight berry
or nut-bearing trees and ten conifers per ha. Additional
guidelines for retaining super canopy trees, conifers in
a hardwood stand, hardwoods in a conifer stand, etc.,
are available in the Ontario Tree Marking Guide (see
Appendix 2).
66

A Landowner’s Guide to Careful Logging
✥✥Retain a diversity of species and age classes in the
woodlot for wildlife habitat, cover and food.
✥✥Rehabilitate areas prone to erosion by seeding or
planting shrubs that wildlife can use for food and cover.
Section 8.0
CLPs for handling and disposing of
hazardous materials
The proper storage, handling and use of oils, fuel,
lubricants and other hazardous materials during logging
is critical for the protection of human health and the
environment.
Use the following careful logging practices when dealing
with hazardous materials:
✥✥Designate specific areas for equipment fueling and
maintenance. When selecting these sites, choose areas
that are level and situated well away from water or
wetlands.
✥✥Have a spill kit on site at all times and ensure that all
workers know how to use it. At a minimum, the kit should
contain a shovel, plugs and clamps to control leaks in
hydraulic lines, a container to catch leaking fluids and
absorbent material to soak up fuel leaks.
✥✥In the event of a lubricant or fuel spill, place any
contaminated earth in a sealed container and dispose of
it at an approved facility.
✥✥Ensure that waste lubricants and their containers
are stored in leak-proof containers until they can be
transported off site for reuse, recycling or disposal at an
approved site.
✥✥When possible, use biodegradable oils and lubricants in
your equipment to reduce risks to the environment.
Know the laws for
using, transporting,
handling and
disposing of
hazardous
materials, their
containers and
wash waters.
For assistance with
spills of hazardous
materials, call the
Ontario Ministry of
the Environment’s
Spills Action
Centre Hotline at
1-800-268-6060.
67

Stabilize exposed soils by seeding grasses to minimize erosion. Native,
non-invasive grass species are preferable. When selecting a seed mixture,
consider factors such as site condition, soil moisture, time of year, degree of
shading and how quickly the soil needs to stabilize.

A Landowner’s Guide to Careful Logging
9.0 Post-Harvest
After harvesting operations, it is important for the
landowner or logging contractor to leave the woodlot in
the best condition possible.
Section 9.0
At the end of harvest operations, the following careful
logging practices will help to ensure that future problems
will not develop.
CLPs for closing out harvest operations
Take the following steps to close out harvest operations:
✥✥Remove all garbage from the harvest area.
✥✥Stabilize any exposed soil (i.e., on landings, road cuts,
trails, etc.), that may be prone to erosion, with seed or
mulch.
✥✥Smooth or fill in any ruts and install water diversions
(water bars) on skid trails, roads and landings where
erosion may be a problem.
✥✥Remove all temporary water crossings and stabilize
banks as required.
✥✥If your woodlot is used by the public, post signs warning
of alterations to trails and roads.
✥✥Inspect the harvest site periodically to ensure that your
erosion control measures remain effective. Maintain
these controls as required.
✥✥Update your woodlot
management plan
(new inventory) and
monitor the effectiveness
of the treatment.

A Landowner’s Guide to Careful Logging
Appendix 3: Logging Damage Guidelines
After logging, a minimum of 90 percent of the good-quality
residual stems should be free of major damage. Skilled
loggers and operators can achieve a higher damage-free
standard (e.g., 95 percent) during operations. Table 2
presents recommended guidelines for assessing logging
damage to residual trees.
appendix 3
Walk through the harvest area to get a preliminary
indication of the level of logging damage. If there is no
damage or only minor occurrences, then there is no need
to conduct a more formal damage appraisal.
Should an appraisal be warranted, do a random sample
using a strip cruise sampling technique. Ensure your
sample covers all areas where logging harvest operations
occurred. Take measurements where damage occurs along
the sample line (including areas where your survey line
intersects with skid trails). Do not sample along skid trails,
in landings, on roads or outside of the cut area.
To conduct the assessment, walk a straight line through the
harvested area and count all trees (greater than ten cm in
diameter at breast height) on either side of your line (e.g.,
a ten-m strip). To calculate the percent damage, count all
trees in the strip and note trees that are damaged. Based
on this tally, calculate the percent damage (i.e., for a 50-
tree count with five damaged trees, the percent damage is
ten percent. Therefore, 90 percent of the sample was free
of damage).
During the assessment, take note if some of the damaged
trees were used as bumper trees, whether damage is
confined to lower-quality trees (this sometimes happens
if the logger felled or skidded trees towards these trees
81

A Landowner’s Guide to Careful Logging
in order to protect those of higher value) or if damage is
concentrated on higher-quality stems (unscrupulous loggers
may damage better quality trees in order to harvest them).
Additional information on how to conduct a logging
damage survey is provided in A Landowner’s Guide to
Selling Standing Timber. A good reference for general
information on planning and conducting forest sampling is
Making Cents out of Forest Inventories: A Guide for Small
Woodlot Owners, available from the LandOwner Resource
Centre (see Appendix 2).
Table 2: Guidelines for Assessing Logging Damage
Type of Injury A wound or injury is considered major when:
Bark scraped off: Trees 10-31 cm diameter at breast height (DBH)
Any wound greater than or equal to the square of the
DBH (i.e., for a 10-cm tree a major wound is greater
than 100 cm 2 )
Trees 32+ cm DBH
Any wound greater than 1,000 cm 2
Note: Wounds on yellow birch (or ground contact
wounds on other species) are considered to be major
at 60% the size of the above for all size classes (i.e.,
60 cm2 for a 10 cm DBH tree or 600 cm2 for any
tree 32+ cm DBH).
Broken branches More than 33% of the crown is destroyed.
Root damage More than 25% of the root area is destroyed or
severed.
Bole of tree broken off Any tree.
Bent over
Any tree tipped noticeably.

Directional felling. Felling trees so that they fall in a
predetermined direction that will cause the least damage to
standing timber or the site.
Drainage structure. Any device or land form constructed to
intercept and/or aid surface water drainage.
Erosion. The incorporation and transportation of soil
particles by wind, water or ice.
Felling. The act of cutting down a standing tree.
Ford. A low-water crossing where you ford or drive through
the watercourse. Fords are an alternative to culverts on
roads and trails and are only used in limited, specific
circumstances.
Grubbing. Removal of stumps, roots and vegetable
matter from the ground surface after clearing and prior to
excavation.
Harvest. The process of cutting and removal of trees from a
forested area.
High-water mark. The point on the bank or shore up to
which the presence of water is so continuous that it leaves
a distinct mark, either by erosion, destruction of vegetation
or other easily recognized characteristic.
Inslope. A road design feature that slopes the road surface
toward the inner or uphill side of the road to facilitate
drainage.

Intermittent stream. A stream that, under average
precipitation conditions, only flows a part of the year. These
streams may or may not have a defined bed and banks of a
permanent nature.
Landing. The area where timber is collected, cut up and
sorted into various products prior to loading for transport.
Leaner. A tree that leans excessively.
Lodged tree. A tree leaning against another tree which
prevents it from falling to the ground.
Main line. A braided wire or a synthetic fibre cable that is
attached to the winch on the skidder, used to pull trees from
where they were felled to the main skid trail for skidding to
the landing.
Mulch. A natural or artificial layer of plant residue or other
materials covering the soil that conserves moisture, holds
soil in place, aids in establishing plant cover and minimizes
temperature fluctuations.
No-disturbance zone. A strip of vegetation left intact along
a lake, stream, wetland, etc. during and after logging.
Outslope. A road design feature to shape the road surface
to cause drainage to flow toward the outside shoulder
(opposite of inslope).
Peak water flow. The highest flow level of a watercourse
which will recur with a stated frequency.
Prescription (stand prescription). A stand prescription is a
planned treatment of a forest site designed to change the
current stand structure or condition to one that meets forest
management objectives.

Residual tree/stem. Individual trees retained after a
harvest.
Rip rap. A layer of rock or other large aggregate that
is placed over soil to protect it from the erosive forces
of flowing water (e.g. to protect stream banks, bridge
abutments, inflow end of a culvert, etc.).
Rutting. A depression made by the passage of a vehicle or
equipment.
Riparian area. The area where land and water meet.
It is a transition zone containing upland and aquatic
vegetation, soils and a variety of wildlife habitat unique to
these areas.
Sediment. Solid material, both mineral and organic, that is
in suspension and being transported from its site of origin
by forces of air, wind, water, gravity or ice.
Seeps/seepages. Typically found along lower slopes, they
are small areas where groundwater discharges slowly; the
soil will remain saturated for much of the growing season.
The water flowing from a seep is true groundwater, not
surface runoff.
Selection harvest/cutting system. Individual trees or groups
of mature and/or unhealthy trees are harvested on a
selective basis. Most trees are retained, and a variety of
age classes are present in the forest following harvest. An
uneven-age stand results.
Shelterwood harvest/cutting system. A harvesting method
in which trees are harvested in two or more successive cuts
to provide seed or protection for regeneration. An evenage
stand results.

Silt fence. A temporary barrier used to trap sediment-laden
runoff from small areas.
Silviculture. The art and science of controlling the
establishment, growth, composition and quality of forest
vegetation for a full range of forest management objectives.
Silvicultural System. Described by the harvest method
used, the systems consist of a planned series of treatments
for tending, harvesting and re-establishing a forest stand.
The three main systems used in Ontario are selection,
shelterwood and clear-cutting.
Skidding. The process of moving (skid/drag) logs or felled
trees from the stump to a landing.
Skid humps. A small natural bump (hump) in a skid trail that
diverts surface water runoff from the trail to minimize soil
erosion.
Skid trail. A temporary nonstructural trail for logging
equipment to drag or carry felled trees or logs to the
landing.
Slash. Any tree tops, limbs, bark and other wood debris left
after a timber harvest.
Slope/grade. Degree of deviation of a surface from the
horizontal, measured as a numerical ratio, as a percent
or in degrees. Expressed as a ratio, the first number is the
horizontal distance (run) and the second number is the
vertical rise.
Spill kit. An emergency kit that contains an assortment
of absorbents designed to absorb oil, coolants, solvents
hydraulic fluids, etc, as well as repair putty and plugs, used
to contain and clean up small leaks and minor spills.
Stand. An aggregation of trees that is uniform enough in
species composition, age or condition to be distinguishable
from other parts of the forest in adjoining areas.

Stream. A watercourse that flows year-round, has a
defined channel and banks and is relatively continuous and
connected with larger surface water.
Treed swamps. Are wet, wooded areas where standing
water occurs for at least part of the year. Swamps tend to
have more woody plants than are found in a marsh.
Tree marking. The careful process of selecting trees to be
cut under a shelterwood or selection cutting system, based
on good forestry practices and a prescription.
Water bar. A shallow transverse trench or mound of earth
(berm) constructed across a trail or road to divert surface
water flow towards the roadside ditch or into a dispersion
area.
Wedge. A small plastic or metal device inserted into the
saw cut to prevent a tree from falling backwards, used in
directional felling and to prevent the chainsaw bar from
being pinched.
Wetland. Land that is permanently covered by shallow
water or land where the water table is at or near the
surface. Swamps, fens, bogs, marshes and seeps are all
considered wetlands in this guide.
Windthrow. A tree pushed over by wind.
Woodland pools. Are temporary pools of water that
generally appear in the spring (vernal pools) from snowmelt
or heavy spring rains and sometimes also form in the
fall of the year (autumnal pools). They are found in small
depressions in the forest and generally have no defined
inlet or outlet.
